AisaFENIX
AisaFENIX is a single-optics imager with two focal plane arrays always
pointing at exactly the same spot of the object so
there is no need co-aligning two separate imagers with different
distortions, sharpness, and field-of-view.

Images are captured in the 380 - 2 500 nm spectral region through single
front optics and a single input slit, keeping all wavebands
spatially perfectly co-registered independently of the distance
to the target.

AisaFENIX employs a “single optics dual channel imaging spectrograph”
which, in spite of the single input slit, has two diffraction gratings,
one optimized for VNIR and second for SWIR region. Also, two focal plane
arrays (FPA), a state of the art CMOS and cryogenically-cooled Mercury
Telluride Cadmium (MCT), are employed in order to maximize sensitivity
and signal-to-noise ratio (SNR) in both spectral regions. With two FPAs,
different exposure times can be applied in the VNIR and SWIR region
in order for optimal adaptation to various spectral illumination conditions.
